摘要
The concentration of an anionically charged polymer in an aqueous solution is determined with a thin solid film having a polymer matrix and a cationic dye. A sample of an aqueous solution containing at least one anionically charged polymer to be tested is applied to the film sensor. The absorbance of the film sensor is measured after the sample has been applied. The absorbance of the film sensor is then compared with a calibration curve of the absorbance of samples containing known concentrations of the anionically charged polymers to determine the concentration of anionically charged polymer in the sample.
